To all whom it may concern:

Be it known that I, FRED R. MONROE, a citizen of the United States, and a resident of Middletown, in the county of Orange and State of New York, have invented certain new and useful Improvements in Fluid- Treating Devices, of which the following is a specification.

My invention relates to apparatus for the germicidal treatment of fluids in general, and the construction thereof is so designed as to adapt it especially for the heating or cooling of milk, in order to destroy bacterla and other microorganisms which the liquid may contain.

A preferred embodiment of my invention is illustrated on the accompanying drawings which are a part of this specification, and upon which the same characters of reference indicate the same parts throughout the several views.

On said drawings: Figure 1 is a vertical transverse section of my apparatus; taken on the line 1 1 of Fig. 2; Fig. 2 is a plan of the same with the lid or cover removed; Fig. 8 is a side elevation, showing an outside view of my device; Fig. 4 is a view of a detail forming one of the inner parts of my invention; Fig. 5 is a similar view showing another detail; Fig. 6 is a perspective view of the spreader which distributes the fluid treated in my invention; and Fig. 7 is a horizontal section of the removable bottom of my fluid treating device.

To describe the invention shown by the drawings in detail, I employ the numeral 1 to indicate a casing to which the fluid or liquid to be treated, such as milk, is supplied by a pipe 2. The fluid enters the caslng by an opening 4 in the lid or cover 3. As Wlll be readily understood the pipe 2 may have any kind of controlling valve, and the lid be provided with handles 3 to remove the same. This lid has a peripheral flange 3 which engages a similar flange around the upper rim of the casing 1, and the two flanges are held together without packing by bolts or other fastening means. The end of the pipe 2 may simply project through the opening 1, or a packed joint may be employed if desired. After entering the casing the fluid encounters a distributor 5 which spreads it,

other tubes 6 surrounding the first tubes to the upper part of the casing and passes out by a pipe 8. This pipe 8 leads to a conduit 9, and this conduit 9 is joined by a pipe 10 to the chamber 7 to enable the chamber 7 to 11 which surrounds all the tubes 6. I also provide the casing with a removable hollow bottom 12, which communicates with the chamber 11. The agent for heating or cooling enters the chamber 11 and passes therefrom into the bottom 12, and thus the fluid is acted upon not only while it is in the tubes, but in the chamber 7 also.

The casing 1 is provided with a plate 13, forming a top, which is lowered below the level of the upper edge of the casing; and another plate 14;, above the lower edge of the casing. Between these two plates the chamber 11 is located, as will appear from an inspection of Fig. 1. The upper plate has a raised central section 15 and a peripheral section 16, and a rim or flange 1T surrounds the section 15 to prevent fluid from flowing from the section 15 directly to the section 16. These plates-13 and 14 hold the tubes 6 in position by means of apertures into which the upper and lower ends of the tubes are inserted. As will be understood the tubes 6 pass through the chaml er 11, but do not communicate therewith.

As shown upon Fig. 1 the section 15 has its surface depressed around the central group of tubes 6, which have perforations 19 adjacent the depressed portions, so that fluid after passing the spreader or distributer enters the tubes through these perforations. Each of the tubes 6 receives an inner tube 20, the upper end of which has a head 21. These heads rest upon the upper ends of thetubes 6, closing the same, and holding and outer tubes.

20 are placed in the tubes surrounding the central group of tubes 6, and these innertubes for the remaining tubes 6 have heads 23 which enter the outer tubes. These heads 23 may have any suitable means such as projections from their sides to prevent them from entering tubes 6 too far, and they also have notches or recesses 24 to enable fluid to pass out of the tubes, these notches forming ports for the passages between the inner The inner tubes here referred to will of course have means to hold them in central position with respect to the outer tubes, the same as, above. The inner tubes for all the tubes 6 merely serve to keep the fluid in contact with the inner surfaces of the tubes 6, to enable me. to cool or heat the fluid in the most eflicient manner. I

may therefore make these members in the shape of tubes 20 as shown, or in the shape of solid rods, if desired. I prefer to make them in the shape of tubes, however, and I provide the heads 21 and 23 with short pipes 22 to admit air into them. The upper ends of these pipes 22 are turned down, to prevent fluid getting to the inside of the tubes 20.

To make the spreader or distributor 5- which distributes fluid to the inner group of tubes6, I employ a sheet of metal or through the apertures as will be readily understood. On the top of thespreader I place acup-shaped body 29, having preforations 30 near the bottom of. the same. This body is centrally located, and isplaced so as to be directly beneath the end of the pipe 2. It receives the incoming fluid or other liquid, forms a pool, which in; the case of milk prevents splashing or other agitation, and by means of the openings 30 causes the fluidv to pass out on all sides of the same and flow all over the surface of the member 25. This cup-shaped member is shown as made separate, but it may be made integral withsheet '25, as by forming a depression in the center, and omitting the openings 30.

' It may also be made in the shape of an up standing rim or flange with the perforations included. The spreader is further-provided with peripheral projections 26 to center it on the section 15. To conduct the fluid from the casing I employ the pipe 8 as above noted, and I locate a thermometer 31 in this pipe to register the; temperature of thev fluid after-treatment. This pipe 8 also includes a glass or other transparent section 32, so

- that any impurities may be seen as the fluid flows out. Communication between the con vide the latter with a flange 46,

outlet pipe 8. section 15 is higher than the section 16 the duit 9 and the pipes 8 and 10 is controlled by a valve 33. To supply a heating or cool- 111g agent to the chamber 11, I locate two coils of pipe 34 therein, one at the top and the other at the bottom. These coils are perforated, and each is connected to a steam pipe 35 and a water or brine pipe 36. A valve 37 controls these pipes, and from the valve to the coils 34 leads a pipe 38. A drain connection 39 may be added if desired. The valve 37 permits either of the pipes 35 or 36 to supply the coils 34, and permits the coils to be drained when necessary.

Communication with the bottom 12 is established by a pipe 40, which has its upper end bent up into proximity with the highest part of the chamber 11, terminating just below the section 15, and having a perforated cap 41 to close the end. This pipe passes out through the side of the casing and is joined to a pipe 42. This pipe 42 makes a shpjoint connection with a bent-up pipe 43 leading to the inside of the removable ;bottom section 12, and from this bottom the contents are drained by way of a connection 44. This connection may be bent up, so

that the contents of the bottom may never :separated from the casing.

To hold the bottom on the casing I proand the bottom with a matching-flange 41'. The flange 47 is grooved over its whole extent, to receive packing 48, and the two flanges are securely held together to obviate any leakage between the flanges. I also provide the bottom with baflie plates 45, which are substantially V-shaped in arrangement, and

placed so as to divert the incoming cooling or heating agent and prevent it from flowlng directly through the bottom and out at the pipe 44. I also provide the casing with ;legs 49, preferably three in number at the sides, and the dimensions of the bottom will be such that the bottom can be drawn out between any two of the legs when the bottom is to be removed. A drain cock 50 for the bottom and a draincock 51 for the chamber 11 are added to enable contents to be quickly removed when necessary.

From this description the manner of operation, utihty and advantages of my lnvent1on Wlll be clear. The fluid enters at the iopening 4, passes over the spreader 5 and into the central tubes 6, down into chamber 7, and up through the other tubes 6 to the Owing to the factthat the substance treated, such as milk, flows down to the chamber 7 and up to the outlet under its own head, and no pumps or other devices to force the milk through the casing are needed. The outlet 8 is placed as near the level of the section 16 as possible. If the milk or other liquid is to be heated, the valve 37 is turned to supply water to the chamber 11, and then to supply steam to heat the water. The chamber 11 and bottom 12 thus become filled with water at the required temperature and it will be observed that the bottom does not fill with overflow from the chamber 11 till the water therein rises almost to the level of the section 15. This is because of the upturned end of the pipe 10. The milk is thus subjected to the action of heat in the tubes 6 and in the chamber 7, and the action of the device is rapid and efficient.

If, however, the milk or other liquid isto' be cooled instead of heated, brine is run into the chamber 11 from the pipe 35 to the perforated coils 34c, and the chamber and bottom then become filled with a cooling agent instead. The action is the same in both cases. A suitable thermometer can be joined to the pipe 38, to register the temperature of the agent entering the chamber 11. The milk or other fluid can be withdrawn from the casing by way of the pipe 10 instead of the pipe 8 if desired, or partly by way of pipe 8 and partly by way of pipe 10. If any impurities are in the milk they will be seen through the section 32, and the apparatus can then be stopped till the cause of the trouble is ascertained and removed. Ordinarily the milk will all be withdrawn through the pipe 8 and the pipe 10 used only at the end of the process to drain the chamber 7. The chamber 11, as above stated, can be drained by the cock 51 and the bottom by the cook 50. The slip joint between the pipes 12 and 43 enables the bottom to be readily removed and replaced, and as shown, the bottom 12 will have suitable handles and casters to enable the same to be easily moved about.

My apparatus is exceedingly efficient, yet simple in construction, and it can readily be cleaned by taking off the cover 3, bottom 12, and removing the inner tubes 20. The parts will be of suitable materials, and I prefer to make the plates 13 and 14 of sufficiently heavy stock to enable them to support the tubes 6. All the piping willbe of sanitary design, with elbow and T couplings, to enable it to be taken apart for cleaning purposes.

It will be understood of course that the milk or other fluid will not be fed in too rapidly, and that the central tubes 6 will be in such numerical ratio to the balance of the tubes 6 that there will be no overflow at the flange 17.

I prefer toadmit air through the short pipes 22 to the inner tubes 20 because if the heads 21 and 23 be entirely imperforate, the

action of the milk, in case the chamber 7 fills up and the level of the milk rises above the top of the chamber in the tubes 6,will tend to draw the air in the tubes 20 out of the same by aspiration or suction. In this way a partial vacuum will be produced, and a column of milk will be maintained by atmospheric pressure in each inner tube as long as the general level is above the top of the chamber 7 or bottom of the tubes 20. These columns of milk in the inner tubes will be higher than the level of the milk in the outer tubes 6 and will in a measure be shielded from the action of the heating or cooling agent in the chamber 11 and the action of the device interfered with. The short open ipes 22 prevents the formation of these co umns by exposing any milk in the tubes 20 to atmospherlc pressure, and

when the general level of the milk in chamber 7 falls below the top of the chamber 7, any milk in the tubes 20 will flow out. By continuing the flange 17 up to the cover 3 and providing suitable packing I can even adapt my apparatus for the treatment of gases.

I wish to have it understood that I do not limit myself to the exact arrangement of parts shown on the drawings and described in this specification. On the contrary I desire to reserve to myself the right to make whatever changes in the shape, size and arrangement of the parts fairly fall within the scope and spirit of my invention.
